Crash Offsets

Still crashing in dalib.dll at 00004353

According to the code, this crash apparently happens when the server starts hosting. It is in the function call CDPServer::GetHostAddresses()

I might recall having this crash on GC ages ago. I believe it was related to a corrupt character file, causing a stack corruption which some how ended up in this function. I’m sorry, I’m not more certain that this.

I’m not sure your first suggestion about the boot.ini applies to us as we don’t use FLHook.

The second interests me but, I know each player character has been ‘cleaned’ by FL PlayerCleaner on more than one occasion, and FLAC is not identifying any attempts to log in with corrupt player chars.

So, short of doing a player wipe, how do you find the corrupt player char(s) if that’s indeed the problem?

As clarified previously, FLAC didn’t form from FLHook. They both use a similar approach because that’s the approach that’s needed but the sources are significantly different enough for them to be completely separate of each other.

The crash offset that is being raised seems not to be being triggered by FLAC and likely wouldn’t be by FLHook either as the errors appear to be triggered by FL itself. Whether further back along the line there’s an issue with the hooking functionality that’s causing the circumstance I can’t tell so far and there’s little to suggest that that is the case.

Unfortunately I’ve virtually exhausted options from my own investigations so far (prior to the post) but will continue to dig and will post if there’s anything new I figure out.

That MS boot.ini workaround refers specifically to servers using AMD procs. We have an Intel proc. Would running that workaround cause any issues or help at all?

going through player files as we speak. Anyone know of any tools that can identify a corrupted player file? I’m using FL PLayer Cleaner to clean everything up, but I’ve been using it for months and still have probs. Willing to try another tool.

Not only for Amd

Robocop try /ONECPU

Enable in control panel - where power setting is - all power settings t “on”

Disable in BIOS power management support for CPU

This named Time Drift Bug

In Linux PM-Timer Bug

The boot.ini /usepmtimer is a fix for a FLServer issue rather than FLHook or FLAC. I should have mentioned, we have an Intel CPU.

Also the test server has been running for 12 hours now. Yay!

I’ve implemented the boot.ini workaround, we’ll see what that does for us.

@Helloween, for power options I have set ‘Always On’. Is that what you mean?

What is /ONECPU?

Next reboot I’ll disable BIOS power management support for CPU.

Well, daily misery report again…
implemented that /usepmtimer suggestion in the boot.ini file, no joy. 18 minutes after reboot got the triple .\HookFunction.cpp(887): *** ERROR: Exception in Hook_IServerImpl_TradeResponse (unhandled exception) message and everyone online got booted.

So, the fact that it happens within 18 minutes of a reboot indicates to me that it’s not likely a memory leak, especially when the server often runs fine for hours. It’s after 1630 server time so, this is going to go on now every 15-20 minutes or so as long as two or more players are online. At least until midnight anyway…

AlphaWolf seems to think that traderesponse message is related to NPCs scanning something/someone but I don’t know. Nothing in that regard has been changed and this behavior happens whether the mod is activated or not…

/ONECPU - use one CPU on multiprocessor system
http://en.wikipedia.org/wiki/NTLDR

I still have one problem - flserver frozens with window whitening and flhook window is fine but ofcourse without any response to commands.

All the same - no logs, no events, nothing.

Because all my server are on physical machine i dunno how it will be after restart with /usepmtimer key in boot.ini

Also will try to disable apic/acpi functions in bios - google says must help.

usepmtimer and /onecpu did not help my problem.

Still crashing in dalib.dll.

What causes hash collisions?

Hash functions are very good, but not infallible, so sometimes two different strings will produce the same result. In the vanilla game, there were five collisions (search jflp.txt for clash; createid -s then whatis -t will find them).

Well, here’s my issue in a nutshell and the specific post which refers to my interest in the causes for a ‘hash collision’.

I am stilled behind this crash at engbase.dll (+0x0124bd). I attached an debugger and the debugger always halt at this stack back trace:

The ReadFile is as far as i could find out something with hudframe021004123005 << dunno maybe something from there…

Has anyone an idea what is done here? Has it something to do with graphical problems due to d3d9!CD3DDDIDX8??

–> that seems to be addressed when the server connection is lost

Correction: The stackback trace is:

Still i have no clue what happens at the engbase.dll is there a way to find out what routines are working there? The dissambly looks like:

crash offset is this line:

Any hints would be appreciated. I am bad in understanding this assembler stuff ;(

Are these servers running mods at all? Some of these, if they are mods, sound like simple testing should have picked them up and been recognised…

I know it’s a non contributory post, just this whole thread seemed an interesting concept and made me immediately suspect it’d replace testing and experience (not trying to offend folks )

@Huor: FindSphereCollisions could suggest a sur problem. Then again, looking at it, it looks like the warning is right, so I wouldn’t put too much credence on the trace. It’s a really strange error, since it already tests for ERROR and NULL, so eax appears legitimate, but is not. Furthermore, it looks like it’s telling you what is there, so it really is legitimate, so where’s the error coming from? Or is this just from a breakpoint, not a crash? Is there something I can test myself, or a remote connection?

I am not an server operator - just someone who might understand a bit of that coding stuff - but not at the level of Adoxa ;D

The stack back trace is made from a breakpoint and i have set the breakpoint to the offset where the server is causing crashes (engbase.dll + 0x0124bd) that we are hunting now for some weeks. I overstepped the breakpoint several times but the stack trace was looking always and nearly the same. So i assume that when it really crashes it must be one of these calling routines that may lead to the crash. And i tested it only client sided - the crash happens at the flserver - so it may be wrong what i wrote anyway.

We tried several stuff and it seems this crash offset is the only one remaining. We are using vanilla surs on the server for some weeks so normally that should not be related to it. Spheres are used for several stuff - so could it also have something to do with NPCs crashing into planet or something like this? As we did disable NPCs for some time the error wasnt there. So its really annoying to dont find the reason for this crash.
